You are probably being confused by the following paragraph in the
documentation for the IDLgrClipboard device...

"An IDLgrClipboard object will send Object Graphics output to the operating
system native clipboard in bitmap format. The format of bitmaps sent to the
clipboard is operating system dependent: output is stored as a PICT image on
the Macintosh, as a device-independent bitmap under Windows, and as an
Encapsulated PostScript (EPS) image under UNIX and VMS."

The fact is that, as of version 5.3, the IDLgrClipboard supports bitmap *or*
vector output, to the clipboard *or* a file. The formats supported are EPS
(all platforms), WMF (Windows) and PICT (Macintosh).

Look at the documentation for IDLgrClipboard::Draw, in particular the VECTOR
keyword.
